GEORGE W. DAY, OF GASPORT, NEW YORK.

TRACTOR.

Application filed February 6, 1912.

To all whom it ma concern:

Be it known t at I, Gnoaoe W. DAY, a citizen of the United States,residin at (iasport, in the county of Niagara and btate of New York,have invented certain new and useful Improvements in Tractors, of whichthe following is a specification refcrcnce being bad to the accompanyingrawlll S- he primary object of the present invention is to provide acompact tractor of relatively great power that is comparatively low,makin it especially useful in cultivating orchar s, and the like, inthat it can pass beneath low branching trees.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure l'is a plan view of the tractor,

certain unnecessary details of construction bein r eliminated for thesake of clearness of tlie disclosure. Fig. 2 is a longitudinal sectionalview therethrough. Fig. 3 is a cross section on the line 88 0 Fig. 2.

Fig. 4 is a detail sectional view on the line 4-4 of Fig. 2.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment disclosed, a supporting frame is employed, having anarrow front ortion 5, and a wider rear portion 6,

the said frame comprising side bars 7, having their rear portions bentoutwardly into angular form to provide the said rear enlargement. Theseside bars are connected at their front ends by a cross bar 8, and attheir rear ends by a similar cross bar 9, A pair of spaced bars 10extend longitudinally through the enlarged portion of the frame, and areconnected at their front ends with the side bars by suitable braces 11.

The front end of the frame is supported by steering wheels 12, mountedon stub axles 18, pivoted to a stationary axle 14 that is fixed byspecial rocker to the front end of the frame. These stub axles areconnected by a link 15, havin its ends pivoted to arms 16, carried bysaid stub axles. Any suitable means may be employed for swinging theaxles, in order to turn the wheels. Extending across the wider rearportion 8 of the frame, is an axle 17, on which are mounted tractorwheels 18 that are arranged 5 within the frame, that is to say, arelocated inside or between the side bars, but outside Specification 0!Letters Patent.

the bars 10. Mounted upon the inner sides of these wheels 18, aresprocket wheels 19.

A motor 20, of any suitable type, is mount ed on the front narrowerportion of the frame, and in advance of the wheels. The motor,illustrated, is of a well known multiple cylinder type, but one or moreeylinders may be employed, as desired. The said motor is connected to apower shaft 21 extending centrally and longitudinally of the frame. Thisshaft projects beyond the front end of the frame, where it is providedwith a pulley 22, or other suitable device for transmitting motion.Arranged on the power shaft, directly in rear of the motor, is a flywheel 23. The said fly wheel is connected to the rear portion of thepower shaft 21, by means of a suitable universal joint 24, and directlyin rear of said fly wheel, the said shaft is supported in a suitabletransverse bearing 25.

Located in rear of the axle 17 and dis posed longitudinally of theframe, is a gear case 26, in which is arranged a suitable changeablespeed gearing 27. It will be noted that this gearing and gear case ismounted on the intermediate bars 10, and extends between the tractorwheels 18. T he rear portion of the power shaft 21, is connected to thisgearing, and extends below the axle 17. As a result of this arrangementthe entire mechanism is located very low in the frame. Interposedbetween the motor and the changeable speed gearing, is a reversing gear28 of any well known type, and operated by a suitable lever 29, havinglink connections 30 therewith. The changeable speed gearing is alsoactuated by a lever 31.

Both of these lovers are located on the rear of the machine and adjacentto the seat 03'? the operator, a portion of the standard of said seatbeing illustrated at 32 in Fig. 2. The changeable speed caring isconnected by bevel gearing 33 wit a transversely dis posed driving shaft34 arranged on the rear of the machine, and carrying sprocket wheels 85.Sprocket chains 36 extend around the wheels 35 and around the sprocketwheels 19 carried by the tractor wheels. A forwardly extending drive isthus given to said tractor wheels.

The motor 20 is incloeed in a suitable casing 37, having an open frontend 38, and

provided with an upwardly and forwardly i.

extending rear end wall 39. Located in the rear portion of this casingis a suitable radiator 40 for the motor, and formed in the top of thecasing, between the radiator and the upper edge of the end wall 39, isan air inlet opening 41. A pair of rotary fans 42 are m uiated betweenthe radiator and motor, and are provided 'with pulleys 43, around whichpasses a belt H that also extends around the fly wheel As already noted,the arrangement permits all the mechanism to be very low on the frame,so that the tractor is particularly adapted for the cultivation oforchards, and the like, inasmuch as it will pass beneath the branches oflow spreading trees. This is due, to a great extent, to the provision,whereby the power shaft is dis posed at or belowthe axis of the tractorwheel. The transmission or changeable speed gearing is compactlyarranged w th respect to the tractor wheels, and permits the tractor tobe driven at various speeds. The particular location of the reversinggear is also important, as the machine can thus be driven in oppositedirections at d1fferent speeds, and said reversing gear also performsthe function of a clutch and brake, all being controlled by one lever.The projection of the power shaft in front of the machine, permits theapparatus to be used as a power plant when stationary. The arrangementand structure of the cool ng means is also important, in connection witha machine of this character. It will be noted that the clear air istaken from above,

driven through the radiator by the fans,

and then projected across the motor.

The end wall 39 constitutes. an effective shield for preventing theingress of dust or dirt from the tractor wheels.

From the foregoing, it is thought that the construction, operation, andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size,

shape, proportion and minor details of construction, may be resorted towithout departing from the spirit or sacrificing any of the advantagesof the invention.-
